>I assume this is saving them in a cookie? I'd much prefer to have the input boxes changed so that the browser can handle the passwords in a (presumably) more-secure way.

I really don't understand what you're trying to tell me. Basically, the default is as before. That is a temp cookie for as long as the browser remains open. As soon as it is closed, the cookie is not store on the disk anymore. As for this addition, anyone who would enable that option in their account would mean that they won't have to retype the username and password whenever they start the browser and go to Universal Thread. If you don't want it, don't enable the option. So, as before is still supported.
